I'm 41 and having an 8mo makes me feel every minute of that age, whereas before I had him I felt young and vibrant. I was fit and healthy! Now I feel old and frumpy - but I am working on the frumpy part with some new bras to hold up the puppies, and new hairstyle (short blonde bob) and exercising more/eating better to fit into my pre-baby clothes.
I have a dodgy knee as one of my legs is almost 1cm shorter than the other (I wear orthotics for exercising), and I've been going to physio regularly lately because my back is as stiff as a steel rod and I have de Quervain's tenosynovitis (inflamed tendon) in my right thumb/wrist requiring me to wear a brace to support and limit movement...I'm right handed so this is a real b!tch, particularly with a baby.
So that's a pretty picture isn't it. Poor DH - he met me at my best and now 10 years on I've fallen apart, aesthetically speaking anyway. He looks great after giving up gluten and losing 18kg just from that change in diet.
